The SEC has posted on its website its proposed new Rule 613 under Section 11A(a)(3)(B) of the Securities Exchange Act of 1934 (“Exchange Act”) that would require national securities exchanges and national securities associations (“self-regulatory organizations” or “SROs”) to act jointly in developing a national market system (“NMS”) plan to develop, implement, and maintain a consolidated order tracking system, or consolidated audit trail, with respect to the trading of NMS securities. Comments are due 60 days after publication in the Federal Register.
